11.13.4.1 Setting breakpoints

To set a breakpoint, for example at a call to + in one of your functions:

1. Open the file containing the call in an Editor tool.
2. Ensure the definition is compiled.
3. Position the cursor at the call to + .
4. Choose the menu command Expression > Toggle Breakpoint , or click
in the Editor toolbar, or run the editor command Toggle Breakpoint . The symbol + is highlighted red indicating that a breakpoint is set.

When the breakpoint is reached, a Stepper tool is invoked, allowing you to step through the code, add further breakpoints, and so on. See The Stepper for more information about the Stepper tool.
